CAM ERA-STAN D.

SPECIFICATION forming part of Letters Patent No. 277,650, dated May 15,1883.

Application filed March 3, 1883. (No model.)

To. all whom it may concern Be it known that I, WILLIAM R. WRIGHT,ofPrinceton, in the county of Gibson and State of Indiana, have inventeda new and Improved Camera-Stand, of which the following is a full,clear, and exact description. v v

The object of my invention is to provide for greater range of action andusefulness in camera-stands; and the'invention consists in certainfeatures of construction and arrangement, hereinafter described.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

' Figure l is a perspective view ofa camerastand embodying myimprovements, and Fig. 2 is a vertical section of the stand. Fig. 3 is aperspective view of one of the picture-clam ps.

The tripod A .is of ordinary character, and

through its head a passes the vertical shaft 1),

that carries the head-block and table for sup-- port of the instrument,as hereinafter described.

Upon the tripod-head is a grooved pulley, 0, over which passes a cord,(1, that is attached at one end to the lower part of shaft 7 the otherend of the cord carrying a weight 6, by which the shaft and parts uponit are balanced. The shaft 1) is formed longitudinally with a groove, f,into which the pulley projects, so that the cord at extends in avertical line, or nearly so, to its connection on the shaft at the lowerend of the slot. This arrangement insures a vertical pull of the cord onthe shaft at or near the center, so that binding of the shaft in thehead is prevented, and only a single pulley is required to insure afreemovement. The weight 6 may be inclosed in a tube, or any device whichwill serve as a guide. As shown, it is guided by a headed pin, 9,entering a slot in a vertically fixed bar, 71., so that the weight isfree to rise and fall, but is prevented from swinging. A setscrew, i,serves for clamping the shaft b in position, as raised or lowered.

7c is a head-block, socketed at Z upon the upper end ofshaft b, so thatit may be revolved in a horizontal plane.

Upon opposite sides of block 7- boards or plates m m are attached, at ornear their midlength, by pivot-pins n n, so that the plates in theplates, and on the pins are clamping nuts q. This construction allowsthcinstrument to be revolved or adjusted right and left, and also set onany angle to thehorizon.

To prevent a too free or sudden movement", there are upon blockfriction-springs 1', that bear against the inner surfaces of the platesm.

The copying attachment or boards is fitted to slide between the platesat in grooves formed in the plates, so that the board can be drawn outwhen required for use, and when not in use is disposed of in placebeneath the camera.

Upon one of the cross-bars of plates at are frictionsprings t, bearingagainst the under side of board 8, and serving to retain theboard inplace.

a is a hinged piece, fitted in one end of board I s, for supporting thepictures to be copied, sliding clamps n being provided on the support,so that the pictures can be quickly and properly adjusted. These clamps(shown most clearly in Fig.8) are strips of sheet metal bent to fitaround the support a, and formed with lips n, for taking over the edgesof the picture. The support a is hinged, so as to be raised into anupright position when in use and turned down flat with boards when notin use. in its upright position the support is held by a rubber or otherspring, 10, extending from the board to any convenient point on board 8.

For convenience of the operation, the tripod A is fitted with a table orshelf, consisting of segments a, attached to the head a and legs of thetripod by pins a These improvements add largely to the convenience andutility of the camera-stand without adding to the expense ofmanufacture.

Having thus fully described my invention, 1 claim as new and desire tosecure by Letters Patent- 1. In a camera-stand, the combination, withthe head a of the tripod, of the shaft 2), pro- IOO vided with thelongitudinal groovef, the pnltion-springs 15, substantially as hereinshown leys 0, journaled in said head, the cord d, the weight 0, andmeans for guiding said weight,

substantially as herein shown and described 2. In a camera-stand, thecombination, with the head a of the tripod, the longitudinallygroovedshaft b, and the pulley and cord 0 d, of the slotted bar h, and thebalance-weight 0, provided with the pin g, working in the slot of saidbar, substantially as herein shown and described.

3. In acamera-stand, the combination, with thehorizontallymevolvinghead-block k, of the plates m, pivoted to saidhead-block and provided with curved slots, and the clampingnuts 9,substantially as herein shown and described.

4. In a camera-stand, the combination, with the horizontally-revolvin ghead-block k and the grooved plates m, pivoted to said headblock, of thesliding copying-board s and fricand described.

5. Thefriction-springs 0', combined with head block 76 and oscillatingplates m, as and for the purpose specified.

6. In a camerastand, the combination, with the copying-board s, of thepicture-support 1e, hinged in a recess of the said board, substantiallyas herein shown and described.

7. In a camera-stand, the combination, with the tripod A, of thesegments (0, provided with pins ed, for securing them to said tripod,substantially as herein shown and described.

8. lhe sliding clamps v, in combination with picture-support a and board8, substantially as specified.
